Can't figure this one out for some reason. Here's a basic example. Need to change the main background when hovering on a deep div (in this case, p "1").
main {
background: yellow;
}
.change:hover ~ main {
background: blue;
}
<main>
<div>
<p class="change">
1
</p>
<p>
2 </p>
<p>
3 </p>
</div>
</main>
